hi all, i am facing a problem on a server of one of our client that it, from time to time status led blinks amber and shuts down, and in order to be able to start it up again, i need to unplug it from the power source for few seconds then plug it back.

thank you for your reply Dan, a PCI modem was installed but after this problems appeared i removed it and reformat the server, it worked fine for 1 or 2 month and it reappeared again, so there are no adapters installed on the motherboard.

A system shutdown occurs & I am assuming that the restart happens the next day as indicated by the log events.

Apart from what Dan mentioned in the previous post, I would also look at temporarily unplugging the serial cable that provides the PBX data to a text file (since you did mention that the modem was already uninstalled previously) & observe if the issue still persists. Goodluck.
